SPECIFICATION forming part of Letters Patent N o. 78 7,328, dated April1 l, 1905. Application filed Junel, 1904. Serial No. 210.665.

To all whom it may concern.-

Be it known that L-Josnrn F. EMMERT, a citizen of the United States,residing at Waynesboro, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inVises;

sockets.

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

' This invention relates to vises of the kind shown and described in thePatent N 0. 457,710, issued to me on August 11, 1891; and it consists inthe novel construction and combination of the arts hereinafter fullydescribed and claimed? In the drawings, Figure 1 is a plan view of thevise from above. Fig. 2 is a plan view of the vise from below and partlyin section. Fig. 3 is a side view of the vise, partly in section. Fig. 4is a detail end view of the springclip and its loekingcam.- Fig. 5 is aplan view of the auxiliary vise-jaw. 6 is a detail view of thewasher-segment. Fig. 7

.is a detail view of the ad usting-screw.

A is a portion of a stationary support, such as a bench or Work-table. Bis a socket which is hinged to a plate B, secured to the bench in anyapproved manner, b being the pivot-pin of the hinge. C is the inner andnon-shdable vise-j aw, which is provided with a sleeve 0, which is journaled in the socket B. D is a hollow rectangular bar which slideslongitudinallyin the socket B and which supports the outer and slidablevise-jaw E. F 1s a handle for turning the vise-screwy; which worksinside the hollow bar D in the usual manner and which enga es with a nutf carried by the sleeve 0. These parts do not differ materiall fromthose shown and described in the ereinbefore-mentioned patent.

The supporting hinge-plate B is rovided withtwo sockets 40 near the endof t e bench for receiving a pillar 41 and a stop-pin 42, these partsbeing interchangeable in the Clampin -screws 44 are provided forsecuring the pillar and pin in the sockets, and the pillar is used as asupport for a drilling attachment, (not shown,) which is supported by itover the vise-jaws.

.In order to secure the vise at different angles, abracketG is securedto the under side of the bench A, and a spring-clip g is pivoted to thisbracket by a pin g.

H is a rod which is slidable longitudinally in the spring-clip and whichhas an anglebracket at one end which is pivoted by a pin 71. to aboss onthe lower and rear part of the socket B. Graduation-marks h are formedon the rod H to indicate the angle of the vise. A check-collar H issecured to the free end portion of the rod H. The spring-clip g has twoopposed lugs i i, and one of these lugs, i, has an inclined cam-surfacej.

J is a handle which is pivoted on a pin is, which is secured to thestationary lug i, and this handle has an inclined cam-surface 7', whichworks against the cam-surface y. Stopshoulders 7c are formed at the endsof the inclined camsurfaoes to prevent the handle from being moved toofar in one direction.

The vise is set to any angle by turning it by hand on its pivot orhinge, and it can then be clamped by pressing the handle J downward,

so. as to cause the rod to be gripped by the spring-clip, which isactuated by the said camsurfaces. The cam-surfaces do not wear outrapidly and slip the same as the threads of a screw, as heretofore used,and as the springclip has a large bearing-surface in contact with therod H the said rod is held securely with very little pressure when thespringclip is contracted by the cam-surfaces.

The sleeve 0 is revoluble in the socket B, so that the vise-jaws can beturned around, and in order to lock the sleeve to the socket in variouspositions a longitudinally-slidable locking-bolt 3 is provided. Thisbolt slides in a hole 4 in a lug on the under side of the socket B, andthe end portion of it engages with holes formed in the inner vise-jaw atvarious points. A spiral spring 5 is arranged in the hole 4 behind theend of the bolt 3 and is held in position by a cross-pin 6. A trigger 7is pivoted on a pin 8 in a slot in the side of the socket B, and thistrigger is provided with a nose 9 for engaging with the bolt 3 and astop to bear against the socket and revent the trigger from being movedtoo ihr back. When the boltis retracted by means of, the trigger, thevise-jaws may be revolved on their axis.

A grooved quadrant or arm is secured on the trigger-pin 8 and isprovided with a projecting pin 31 for actuating the trigger. A treadle32 is pivoted to the workbench and is connected with the quadrant by aflexible connection 33, having a take-up 34. In this manner the bolt 3may be operated by hand or by foot, as convenient.

. The face of the inner and non-slidable visejaw C is provided withangular grooves 12 and a rectangular hole 13.

I N is an auxiliary vise-jaw having knife-. edges n on its back, whichengage pivotally -with the grooves 12.

This jaw also has a rectangular stem 0 for engaging loosely with thehole 13. The end portion of the stem 0 has a spring-actuated latch 14,provided with a beveledend 15. This latch slides in a cross-hole in thestem and is pushed back when the stem is placed in the hole. As

vsoon'asthe end portion of the stem projects at the rear of the mainvise-jaw the latch springs forward and holds the auxiliary visejaw inposition, but permits it to rock on its knife-edges and adjust itself tothe angle of any irregular piece of work.

The outer vise-j aw E is ivoted by a pin 18 to a forked head 19 on t ebar D, and the head 19 has radial slots 20, in which a nut 21 isslidable. The vise-j aw E has a central lug 22 on its back, which worksin the fork of the head 19 and which has an inclined slot 23, which alsoengages with the nut 21. The vise-jaw E has also a boss 24 at the end ofthe lug 22, and 25 is an adjusting-screw having a milled head 26'andacollar 27. These parts are similar to the corresponding parts describedand claimed in the hereinbefore-mentioned patent, No. 457,710, and theirfunction is to enable the vise-jaw E to be set at various angles withthe vise-jaw C. When the screw 25 is revolved in one direction, the jawE is inclined in one direction, and when the motion of the screw isreversed the said jaw is moved in the reverse direction. The collar 27is journaled in a recess in the boss 24, and 28 is a washer-segment,which is slipped into a cross-slot 29 in the boss 24 after the screw 25has been placed in position. The

wvasher-segment engages with the collar 27,

- structed in this manner, the washer 28 pre- B15531 AVAILABLE co ventsthe end play of the screw instead of a projection on the cap, as in thehereinbeforementioned patent, No. 457,710, and the parts can be fittedtogether to work more accurately and with less labor and expense.

What I claim is 1. The combination, with a stationarysupport, a sockethinged thereto, and vise-jaws carried by the said socket; of abracketsecured to the said support, a spring-clip pivoted to the saidbracket, a rod pivoted to the said socket and slidable longitudinally inthe said clip, and a handle pivoted to the said clip and provided withan inclined cam-surface for contracting the said clip upon the rod,substantially as set forth.

2. The combination, with a stationary support, a socket hinged thereto,and vise-jaws carried by the said socket of a bracket secured to thesaid support, a spring-clip pivoted to the said bracket, a rod pivotedto the said socket and'slidable longitudinally in the said clip, and ahandle pivoted to the said clip and provided with an inclinedcam-surface for contracting the said clip upon the rod, said clip andhandle being also provided with interlocking stops which limit themovement of the handle in one direction, substantially as set forth.

3. The combination, with a supportingengaging with the said bolt, an armsecured on the said pin and provided with a projection for engaging withthe said trigger, a treadle, and a connection between the said treadleand arm, substantially as set forth.
